title: [Multicentric evaluation of a self-screening questionnaire for occupational bladder cancer].
abstract: OBJECTIVE
  Evaluate a self-screening questionnaire for bladder cancer of occupational origin and analyse an influence of exposure to a carcinogen bladder tumor on prognosis.
  
  
  METHODS
  Five hundred and thirty-one patients followed, between 2005 and 2010, for bladder cancer in two university centers have received a self-screening questionnaire derived from questionnaire KVP 08. Patients who responded positively to at least one of the items were considered to have a self-screening questionnaire "positive". Patients were finally invited to take an appointment for consultation in occupational pathology.
  
  
  RESULTS
  The response rate to self-screening questionnaire was 39.9% (212/531). It was "positive" in 82 cases (38.7%). Among the 82 patients with a self-screening questionnaire "positive", 46 patients consulted in occupational pathology (56%). Occupational exposure to a bladder carcinogen was documented in 91.3% of cases. Among the 22 patients who consulted in occupational pathology with a self-screening questionnaire "negative", an occupational exposure to a bladder carcinogen was documented in 13.6% of cases. The sensibility of the self-screening questionnaire was 91.3%, the specificity 86.4% and the accuracy 89.7%. The relative risk to have an occupational exposure if the self-screening questionnaire was "positive" was 6.69. The analysis of groups "positive" versus "negative" does not reveal any statistically significant difference in terms of tumor aggressiveness and disease-free survival.
  
  
  CONCLUSIONS
  The self-screening questionnaire was considered relevant with good reliability for detection of occupational exposure to a bladder carcinogen.
